This inventionrelates tol an improved form; of

*The principal object oa-the inventionis` the provision of adeviceof ether character described which may be usedin` connection` with shoes of di'erent sizes andshapes yand, in connection with bothright and left shoes.

Another object of this, invention is theprovisin of ya machine ofthe character described which is readily adjustable for shoes of different size and shape and which permits of ready mountting and demounting of the shoe relative thereto.

Preferred' embodiments of this invention are shown in the accompanying drawing in which,

Fig. 1 is a vertical longitudinal section through the device.

Fig. 2 is a fragmentary plan view of the device.

In the embodiment of this invention, as shown in Figs. 1 :and 2, a spreading type of toe block |20 is shown. This toe block comprises a permanently fixed or :positioned inner part |2| flanked xby two moveable side ,parts |22. Compression springs I23 tend to urge these several parts apart. It will be noted that the center piece |2| is connected to the two side pieces |22 by means of :pivotally connected links |25 and |26. When the toe block |20 and the sole plate |30 are moved into position in the toe of shoe 25 a spreading yaction of the two side pieces |22 takes place as a consequence of any forced forward movement of the center piece |2|. At the rear of the sole plate |30 may be formed a hand grip post |30'. This forced forward movement is effected by the following parts: A plate |31 is connected to the center piece |2| in a manner which permits of pivotal movement of the one relative to the other. This type of movement may be provided by forming a curved slot |32 in the center piece |2| and inserting forward curved end of plate |3| therein connected to the plate |3| by means of links |34 and |35 to heel plate |36 and counter block |31 pivoted to said heel plate. A screw |38 extends through an upwardly projecting part |39 of counter block |31 and engages xed pins |40 therein. When the screw |38 is caused to rotate by means `of knob |4| aixed thereto forward or backward movement of said screw is effected through the Iupwardly extending portion |39 of the counter block. The forward end of screw |38 is rotatably xed to U-'shaped member |44 and said U-shaped member is pivotally i'lxed to a second U-shaped member |45. The yokes of the two U-shaped members are opposite each other and it is by means of pins |41 extending through their legs that they are swivelly or pivotally connectedzte cachet-hen. Thezseeond-l U-shaped: plate- |45: is;.,f1l-ed1v.-- mounted.:E on4 thepirater itl.; andy indeed@ its, may; even be;` integraltherewith.,

While the invention has been described in detail and with respect to the preferred rform` shown in the drawings, it is not to be limited to such details and forms since many changes and modiiications may be made in the invention without departing from the spirit and scope of the in,- vention in its broadest aspects. Hence, it is intended to cover any and all forms and modiiications of the invention which may come within the language or scope of any one or more of the appended claims.

I claim:

1. A shoe last comprising a sole plate, a heel plate, a toe block mounted on the sole plate, a counterblock pivoted on the heel plate, and adjustable means extending between the counterblock and the toe block to alter the distance therebetween.

2. A shoe last which comprises a sole plate, a heel plate, a toe block mounted on the sole plate, a counterblock pivotally mounted on the heel plate, pivotal connections between the toe block and the heel iplate and adjustable connections between the counterblock and the toe block to alter the distance therebetween.

3. A shoe last which comprises a sole plate, a heel plate, a toe block comprising a center section fixed to the sole plate and lateral expandable sections on each side of the center section, links connecting the center and lateral connections, a counterblock pivoted on the heel .plate and adjustable connections between the center section of the toe block and the counterblock to alter the distance therebetween.

4. A shoe last which comprises a sole plate, a heel plate, a toe block comprising a center section fixed to the sole plate and lateral expandable sections on each side of the center section, links connecting the center and lateral connections, a counterblock pivoted on the heel plate and adjustable connections between the center section of the toe block and the counterblock to alter the 3 distance therebetween, and pivotal connections between the toe block and the heel plate.

5. A shoe last which comprises a sole plate, a heel plate, a toe block having a center section mounted on the sole plate and laterally adjustable sections on each side of the center section, toggle links connecting the center section with the lateral sections of the toe block, a counterblock pivoted to the heel plate, and adjustable connections between the counter-block and the toe block to alter the distance therebetween and expand the lateral sections of the toe block against the toe of the shoe as the center section is advanced.

6. A shoe last which comprises a sole plate, a heel plate, a toe block having a center section mounted on the sole plate and laterally adjustable sections on each side of the center section, toggle links connecting the center section with the lateral sections of the toe block, a counterblock pivoted to the heel plate, and adjustable connections between the counterblock and the toe block to alter the distance therebetween and expand the lateral sections of the toe block against the toe of the shoe as the center section is advanced, and pivotal connections between the toe block and the heel plate.

7. A shoe last which comprises a sole plate, a heel plate, a toe block having a center section xed to the sole -Lplate and adjustable lateral sections on each side thereof, toggle links connecting the center section and the lateral sections, springs between the center section and the lateral sections normally tending to hold them apart a predetermined amount, a counterblock pivotally mounted on the heel plate and adjustaf ble connections between the counterblock and the center section to alter the distance therebetween.
